My father is on the verge of dying. He has gotten to the point where he can not speak but is still aware. I am expecting he will die within the next day or two. I am doing okay. Because I am not sure when he will die, I have not been taking the Ambien to sleep. I am very tired but that is nothing like how my mother is. She has been going non stop for days now. Thank You for all the support you have given me.
